- COMBINATION LIGHT REFLECTOR AND DIFFUSER.

To all whom it may concern:

Be it known that I, .HARRISON D. Mo

and diffusers for use in connection with incandes'cent lamps, gas burners, and other lamps and illuirnnators, and the object thereof 18 to provldea combination'rlevice of this ,7 class which comprises a reflector and a diffuser detachably connected with the light discharging end of the reflector, the said light discharging end of the reflector being preferably conical in form or flared and the diffuser being concavo-convex in form, and

the light dischargingend of the reflector and perimeter of the difluser being so formed as; to ,snuglyfit together and to form, when' placed together, a circular projection formmg, in cross section; an angleof approximately forty-five degrees, said reflector. and dizfluser being connected-by an open elastic ban h g in. i s nner su l a groove adapted to receive saidicircular projecting gortion and provided with tensional or other the separate parts or ends thereof together.

h invention isfully disclosed inthe following specification, of which the accompa- 'nying drawing, forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which;

Figure-1 is a plan vie of my improved combination light reflector and diffuser, part thereofbeing shown in full lines and art in section; and,Fig. 2 a detail vie'ws owing 1 a modification of the means for securing the diffuser to the reflector;

In the practice of my invention, I provide v a reflector-a which, in the form shown, is of t the ordinaryconical tiype and prov ded at its smaller end with a aring rim or collar on by' which it may be connected with the sup- 7 ort of, an ordinary incandescent electric amp, gas .burner or s1m1lar device.

I also "proyide' alight diffuser b which is preferably con'cayo conve'x in cross section and is made of 1glass andmay becomposedlof' ground Specificatio'n'of Letters Patent. 1 Application filed July 7, 1906. Serial No 325,132,

glass, sandedglass, or if desired said diffuser may be of prismatic construction.

The perimeter of the diffuser and thebase .or'light discharging end of the reflector are so formed as to closely fit together as shown at c in Fig. 1, and the greatestdiameter of the diffuser b is the same as that of the greatest diameter of the light discharging end of the reflector a, and when said diffuser and reflector are placed together as shown in Fig. 1 the outer surfaces or walls thereof form,-in-cross section, an angle of approximately forty-five degrees as shown. at a and said parts are detachably connected by means of an open elastic band (Z grooved on its inner side so as to receive the projecting annular and angular portion formed by the reflector and diffuser when placed together,

and the separate end portions of the open elastic band (ZSIIB connected in the form of construction shown in Fig. 1, by means of a contractile spring e which serves to contract the band d and to securely hold the reflector and diffuser in the position shown in,

Fig. 1.' The reflector a may also be of any preferred construction and t may be of the porcelain type, the inner side of which is colored white and the outer side of which is provided with a coating of different color.

Instead of employing the contractile spring a for the purpose of connecting the end portions of the band d, said ends may be provided with jaws d as shown in Fig. 2

through which is passed a screw In practice I prefe to make t 1e band (I of sheet metal, bent longitudinally, so that it is semi-circular in form in transverse section,

or the said band may be made many desired manner, and instead of consisting of a single piece it may be composed of two or more pieces connected by a'sprmg or springs eor by a screw or screws f VV'lth this con struction the diffuser 11 may be detached from the reflector whenever desired, in order to clean said arts, or the diffuser maybe detached from tli not required.

Having fully described my invention, what I claim asnew and desire to secure byLet-v ters Patent, is j I In a ,device'of the class described, the combination'with a reflector the light-discharging end of which is provided with a flattenedl edge-t0 form a seat, of a diffuser concaveconvex in cross section associated with said e reflector when its use is mew emte with. the fiattensd edge of the i ahargi'ng and of the reflector, the refiectur and diffusar a0 persxtrln an miera projection at the TACQLITZ; tisns 02? me reflector and. difi'usez', band cimhng the reflector and diffuser having an innar side in rezzeive the pmjactingg pv m-refiestor and. difi'user, and. 1111 ms iband, whereby be same is we the meeting port-ions- 01 i'efieetm. and diffuser :i'm' 3101C the same :21 assocmted rclamon.
